He was pronounced dead within two minutes by a paramedic who arrived at the scene just before 4pm.

Senior coroner David Heming said Mr Rowland died of multiple traumatic injuries.

In his submitted testimony which was read out at the inquest today (Thursday, August 6) PC Jason Porter, of Cambridgeshire Constabulary’s collision investigation unit, said Mr Rowland’s sudden steering into the Scania was a likely reaction to the presence of an another lorry which had moved in front of him.

But he added: “The proximity of the Audi to the lorry when it changed lanes is unknown.

“It is unknown if the lorry made a safe manoeuvre or whether Mr Rowland was slow to react to its presence.”

No mechanical defects were found which could have contributed to the collision.

The Scania had been parked in the lay-by for approximately 76 minutes as the Serbian long-distrance lorry driver Milan Zarkovic needed a break having driven, he said, for approximately 14 hours.

In further submitted testimony, eye-witnesses said the Audi had flown into the air after the collision and was opened up “like a tuna can.”

The passengers in the car were taken to Peterborough City Hospital but were not stated to have suffered major injury.

In his summing-up of the inquest, Mr Heming recorded that: “On March 30 2015, the deceased sustained multiple traumatic injuries when he was the driver of an Audi A5 Coupe motorcar that collided with the rear of a parked Scania motor lorry that was in a lay-by on the A1 at Wittering (northbound carriageway).

“The conclusion that I have reached is one of road traffic collision.”
